This patch seemed like a good idea to me; I just checked linux-next,

thought I would send a prod-o-gram to see what the current thinking

I haven't really gotten any feedback on the patch, so it fell on the
floor for a while.  I've managed to get some big system resources to
test the impact of it, and once I've got numbers I'll resend it as
separate patches for scsi and the block layer.
